Will the Fabspeed XperTune Performance Software work on my 991.2 GT3 or GT3 RS?

Yes. The Fabspeed XperTune Performance Software is written for the 2017-2019 991.2 Porsche 911 GT3 and the 2018-2019 991.2 GT3 RS, both with the 4.0L flat-six. It flashes through the car's OBD-II port using the supplied handheld, so nothing needs to be removed from the vehicle.

How is it installed? Do I have to send my ECU anywhere?

No. That is the main reason this product exists. Porsche's latest generation ECUs normally require bench flashing, meaning the unit comes out of the car and gets mailed away. XperTune uses a handheld tuner through the OBD-II port instead, so the ECU stays where it is and the car stays where it is.

Can I return the car to stock?

Yes, at any time, using the same handheld and the same process in reverse. No dealer visit and no shipping is involved. Being able to put the car back to factory calibration quickly is worth as much as the tune itself when the car is going in for service or being sold.

Do I really need a Windows PC?

Yes. The handheld connects to a computer to transfer tune files and Mac OS is not supported. It is the one hard requirement that catches people out, so confirm you have access to a Windows machine before ordering rather than after the handheld arrives.

Does it work with an aftermarket exhaust?

Yes. Maps are available for completely standard cars and for cars running Sport Cats, competition pipes, a full exhaust system and other hardware changes. Tell us what is on the car when you order so the correct map is supplied, since a tune written for a standard exhaust is not the right file for a modified one.

How much power does it add?

Fabspeed quotes 500 hp and 339 ft-lbs stock rising to 525 hp and 358 ft-lbs, a gain of 25 hp and 19 ft-lbs. That comes from recalibrating what the factory map leaves conservative rather than from any hardware change, which is why the software alone is worth fitting before anything else on the car.

Description

Fabspeed XperTune Performance Software for 991.2 Porsche 911 GT3 & GT3 RS

The Fabspeed XperTune Performance Software solves the part of ECU tuning that used to be the worst part of it. The latest generation of Porsche ECUs normally demand bench flashing, which means pulling the unit out of the car, mailing it somewhere, waiting, and doing the whole thing again in reverse if you ever want the car back to stock. XperTune replaces that with a handheld tuner that plugs into the OBD-II port. Flash the tune, drive the car, and flash it back whenever you want without a dealer, a workshop or a shipping label. Fabspeed quotes 500 hp and 339 ft-lbs stock rising to 525 hp and 358 ft-lbs, with maps for standard cars and for cars already running Sport Cats, competition pipes or a full exhaust system.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
